Will AI Power Demand Push ERCOT Beyond Texas? Southern Spirit Transmission Could Accelerate Efforts Toward a National Electrical Grid

With the rapid rise of AI-driven energy needs, Texas’s grid—managed by the Electric Reliability Council of Texas (ERCOT)—could soon become more connected to neighboring states. Currently, ERCOT operates mostly as an "island" with limited power exchange between Texas and the rest of the U.S., and energy primarily flows into Texas via separate DC connections. The Southern Spirit Transmission Project, a high-voltage transmission line running from Texas into Louisiana, would allow ERCOT to export surplus power out of Texas for the first time, increasing flexibility and resilience in the face of growing demand and extreme weather. Learn more about this project on Pattern Energy, KERANews, and Grist.


Southern Spirit would link Texas’s renewable energy resources, such as wind and solar, with neighboring states, allowing geographic and temporal load shifting. This would enable Texas to export energy during peak production times and import energy when demand surges, stabilizing the grid and supporting the transition to clean energy across state lines.


As AI demand grows, connecting ERCOT to a broader grid network could alleviate energy constraints by sharing renewable energy resources across borders. Beyond Texas, California's ISO and the Southwest Power Pool (SPP) are pursuing similar expansions to support a more integrated U.S. grid, allowing states to efficiently balance energy resources. Southern Spirit Transmission could enable Texas to leverage its renewable energy potential while increasing reliability for customers throughout the region.
